MODE OF OPENING AND CLOSING FARM-GATES.

Specification of Letters Patent No. 21,811, dated October 19, 1858.

fo aZZ whom it may concern.'

Be it known that I, I. T. Bocos, of Oincinnati, in the county ofHamilton and State of Ohio, have invented a new and Improved Attachmentfor Gates Thereby They May be Opened and Closed by Persons from aVehicle or on Horseback; and I do hereby declare that the following is afull, clear, and exact description of the saine, reference being had tothe annexed drawings, making a part of this specifica-tion, in which*-Figure 1, is a face or side view of a gate with my improvement appliedto it, the gate being represented in an open state. Fig. 2, is a plan ortop view of the same.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention consists in having a zigzag grooved cam or cylinderplaced near the post to which the gate is hung, said cam being connectedwith a lever which is pivoted to an arm attached to the gate, the aboveparts being used in connection with an automatic gate catch or fasteningand a loaded pawl arm actuating the cam or cylinder, whereby the gatemay be opened and closed at either side, and from a vehicle or on horseback.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A represents a gate which may be constructed in the usual manner, andhinged to a post B.

O, is a horizontal cylinder the axis of which is fitted in bearings a,attached to the post B. The cylinder O, is grooved in a zig-zag manneras shown at Z2, Fig. 2, and to one end of the cylinder a ratchet c, isattached.

D, is an arm, one end of which is itted loosely on the axis ot thecylinder C, and the opposite end has a. weight E, attached. To the armD, a pawl d, is attached, said pawl catching into the ratchet c.

F, is a horizontal lever which is secured in the post B, by a fulcrumpin e. One end of this lever has a pin f, attached, which pin fits inthe groove b, ot' the cylinder and the opposite end is pivoted to an armG, which is attached to the gate A. To the lower end of the arm D, twocords or chains g, g. are attached, and these cords pass over pulleys7L, which are attached to posts H, H,placed one at each side of the postB. To the end of the axis of the cylinder opposite to that where the armD, is placed a bar z', is attached atits center, and each end of the baris bent at right angles to its main portion, as shown clearly in Fig. 2.

I, is an ordinary drop latch which is attached to the gate A, and whichts in beveled catches j, j, attached to posts I-I, K, to which the gateis secured, the gate being secured to one post H, when in an open stateand to the other post K, when in a closed state. To the inner end ot thelatch I, a series of jointed levers It, are attached, the end of theterminal lever of the series k, being, when the gate is closed, belowone end ot the bar z', and in the path of its movement, see bothfigures, in which the position of the terminal lever k, when the gate isclosed is indicated by dotted lines. The position of the several levers71:, is shown clearly in Fig. l.

To the post B, a system of levers Z, are attached, the position andarrangement of which are plainly shown in Fig. l. To the end of theterminal lever 7c, a pin m, is attached, which pin projects under theend of the uppermost lever Z, when the gate A, is open, as shown clearlyin Fig. 2.

The operation is as follows: By pulling a cord g, at either side of thegate the armD, will rotate the cylinder O, in consequence ot the pawl(Z, catching into the ratchet c, and the zig-zag groove ZJ, will actuatethe lever F, and arm G, and the gate will be thrown open and the latchI, made to catch into the catch y', of either post H, K, one part of thezig-zag groove throwing the gate in one 'direction or opening it, andthe other closing it. The cylinder C, it will be seen is rotated in onedirection only and the gate consequently can be both opened and closedat either side ot' it. When the cords g, are pulled the latch I, israised previous to the actuating of the levers F, G, by the bar z',which actuate the levers 7c, when the gate A, is closed, and actuate thelevers Z, when the gate is open, said levers raising the drop latch sothatthe gate may be free to open and close when actuated by the leversF, and G. The weight E, brings the arm D, in a vertical position eachtime the cords g are released from the pull.

I am aware that levers have been applied to gates connected with cordsand arranged in various ways for the purpose of allowing the gate to beopened and closed by persons from a vehicle or on horse back. Itherefore do not claim separately the levers herein described; but,

I claim as new and desire to secure by Letters Patentcylinder or cam C,pawl arm E, lever F, 10 and arm Gr, the drop latch I, arranged with thelevers 70, Z, so that the latch may be operated automatically asdescribed.

l. The orooved cylinder or cam C actuated by thbe loaded paWl arm E, andlised in W' T' BOGGS connection with the lever F, and arm G, asWitnesses:

and for the purpose set forth. O. D. WHITE,

2. I also claim in combination With the l GEO. W. ROGKEY.
